PSV Installation-Guide ; 6. Inlet PSV shall "free draining" to avoid liquid accumulation. ; 7. Block valve at inlet line ( if any) shall be LO and LC for spare Installation of the drip pan elbow has its own guidelines. o Never attach the vent discharge piping directly to the safety valve. This would place undue stress Safety Valve Installation and Operating Instructions. Pre-Installation Handling. Pressure relief valves are designed to protect equipment from overpressure. PSV Testing Procedure · The valve should open up at the set pressure of the PSV. · For the overpressure scenario, the discharge fluid rate shall be as per the PSViv) Define set pressure, over pressure and relieving pressure of the PSV depending upon maximum allowable working pressure and accumulation as per API Standard Increase the diameter of the pipe. · Ensure that any corners are suitably rounded. · Reduce the inlet pipe length. · Install the valve at least 8 to 10 pipe
